Milltek Performance Exhaust System for BMW M240i G42 xDrive with OPF, Cat Back Bypass, Part No. SSXBM1222

Give your BMW M240i G42 xDrive the soundtrack and flow it deserves with the Milltek cat back OPF bypass system, part number SSXBM1222. This UK engineered upgrade bolts up cleanly to the factory rear finishers, needs no cutting of the original pipework and is tailored specifically for vehicles fitted with a petrol particulate filter. The result is a sharper, more engaging tone and freer breathing without compromising day to day refinement.

Crafted from high grade T304 stainless steel and hand finished in Britain, the Milltek system is built to last. Precision mandrel bends maintain a constant radius for smooth gas velocity, while carefully developed acoustics deliver a refined, sporty note with minimal cabin drone. We have installed and used this system ourselves on customer cars and feedback has been consistently positive for fit, quality and the transformed sound.
